[sdiy] "scanner" or voltage-controlled routing?( vc stage-address)

[Andreas Wetterberg]

Hi Dave, thanks for getting back to me!

What I have in mind is the other way around: Routing a simple gate 
source to different destinations - this would have the benefit of 
allowing me to split it into as many "rows" as I'd like, etc.

I hope that makes a bit more sense? The (very cool) example below shows 
8 sources that can be switched to any of two outputs. I'd like one 
source that can be sent to any of x outputs - doesn't have to be a 
full-on VC switch as such, I just need to run +ve into different 
destinations.

Andreas.
